Analyze the key features of the graph of the quadratic function f(x)=-x^2+2x+10. Does the parabola open up or down? Is the vertex a minimum or a maximum? Identify the axis of symmetry, vertex and the -intercept of the parabola.

ANSWER

450lb

EXPLANATION

If the weight, m of an object on the moon varies directly as the weight of an object e, on the earth, then we can write the mathematical statement,.

We introduce the constant of proportionality to obtain,



When, m=95, e=570,

This implies that,






The equation now becomes,



We want to find e, when m=2700,
